Description

[Technical Field]

[0001] This invention relates to the field of injection molding technology, and in particular to an injection molding method for embedding carbon fiber plates and its products. [Background Technology]

[0002] Insert injection molding is very common in modern industry, and many everyday tools and products are made using this process. However, the current injection molding process for embedded carbon fiber sheets cannot be used for material removal because the product edges are visible. Furthermore, since the lower end of the carbon fiber sheet is suspended before injection and has no support during mold closing, there is often excess glue at the joint of the carbon fiber sheet after injection molding. As a result, it cannot pass the appearance quality inspection, affecting the product qualification rate and making it impossible to manufacture using existing methods.

[0003] Therefore, it is necessary to improve existing technologies. [Summary of the Invention]

[0004] The technical problem to be solved by the present invention is that in the current injection molding process of embedded carbon fiber sheets, the lower end of the carbon fiber sheet is suspended before injection and has no support when the mold is closed and pressed. After injection molding, this often leads to problems such as glue overflow at the joint of the carbon fiber sheet.

[0005] The solution to the technical problem of this invention is: an injection molding method for embedding carbon fiber plates and the product thereof, comprising the following steps:

[0006] S1: Injection molding auxiliary plastic strip;

[0007] S2: Cut the pressing auxiliary plastic strip to the required length;

[0008] S3: Process the carbon fiber board to the required size;

[0009] S4: Adhere the pressing auxiliary plastic strip to the carbon fiber board;

[0010] S5: Place the carbon fiber board with the adhesive bonding auxiliary plastic strip into the mold;

[0011] S6: Perform injection molding.

[0012] The plastic resin used in S1 is the same resin used in the injection-molded product in S6.

[0013] The plastic resins used in S1 and S6 can be thermoplastic resins or thermosetting resins.

[0014] The pressing auxiliary plastic strip produced in S1 is used to bond with the carbon fiber plate and support the carbon fiber plate when the mold is closed, so that there will be no glue overflow at the joint between the injection molded carbon fiber plate and the molded product.

[0015] The cutting method in S2 can be manual or machine cutting.

[0016] The bonding method in S4 can be manual or machine bonding.

[0017] In addition, the present invention also includes a product manufactured using an injection molding method for embedding carbon fiber plates. [Attached Image Description]

Detailed Implementation Methods

[0021] To further illustrate the technical means and effects of the present invention, the following detailed description is provided in conjunction with the embodiments of the present invention and their accompanying drawings.

[0023] Example 1

[0024] Please see Figures 1-3 ,

[0025] This embodiment uses the steps provided by this method for manufacturing:

[0026] S10: Injection molding auxiliary plastic strip (2);

[0027] S20: Cut the pressing auxiliary plastic strip (2) into several pieces with a length of 20mm, a width of 0.9mm, and a height of 0.6mm;

[0028] S30: The carbon fiber board (1) is processed to have a length of 300 mm, a width of 8.5 mm, and a height of 0.8 mm;

[0029] S40: Adhere the cut pressing auxiliary plastic strip (2) to the carbon fiber board (1);

[0030] S50: Place the carbon fiber plate (1) with the bonded pressing auxiliary plastic strip (2) into the mold;

[0031] S60: Injection molding.

[0032] The plastic resin used in S10 is the same resin used in the injection-molded product in S60.

[0033] The plastic resin used in S10 and S60 can be a thermoplastic resin or a thermosetting resin.

[0034] The pressing auxiliary plastic strip (2) produced in S10 is used to bond with the carbon fiber plate (1) and support the carbon fiber plate (1) when the mold is closed, so that there will be no overflow of glue at the joint between the injection molded carbon fiber plate (1) and the molded product.

[0035] The cutting method in S20 is manual cutting.

[0036] The bonding method in S40 is manual bonding.

[0037] The bonding position of the pressing auxiliary plastic strip (2) in S40 is the edge of the carbon fiber board (1).

[0038] The spacing between the bonding auxiliary plastic strips (2) in S40 is 5mm.

[0039] The benefits of this invention are that when manufacturing using the injection molding method of embedding carbon fiber plates according to this invention, by injecting a pressing auxiliary plastic strip and bonding it to the carbon fiber plate, the carbon fiber plate is supported during mold pressing and injection molding, thereby preventing glue overflow at the joint between the carbon fiber plate and the molded product. This invention can be widely used in product design with different needs and is a convenient and economical solution.

[0040] It should be noted that the technical principles of the present invention have been described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way.
